ERWIN A. BURKE, or CLEVELAND, omo

To all whom may concern.- I 7 Be it known that I, ERWINA. BURKE,ac'itizen of the United States, residing at Cleveland, in the county of(Juyahoga and State of Ohio, have invented new and useful Improve mentsin Soles and Welts, of which the following is a specification.

This invention relates to soles and welts for l shoes, and particularlyto the means by and the manner in which an outer sole is fastened to awelt.

The object of the invention is to remove a defect incident to thepresent method of attaching the outer sole to the welt, and a furthethread [to pull through the welt for the first two or three stitches,and the subsequent skived down,

working of the shoe in walking is liable to pull through still more ofthese stitches, and I in time the ends of the welt become detached fromthe sole, leaving an opening. Repeated efforts have been .made to devisea means whereby the ends of the welt would be prevented from becomingunstitched or loose, while preserving the good appearance of the parts.v Toremedy the defect indicated, I make a channel across or recess inthe shank; of the outer sole before .it is sewed to the welt. Thischannel or recess receives the ends of the welt, which, instead of beingare left at. their original thick? mess. The c'hannel'or recess has atthe heel end a depth equal to the thickness of the leather used in thewelt, and the channel is tapered or inclines upwardly and forwardlyuntil it comes to the natural surface'of the leather. To give a neatjob, the channel should be at least three-fourths of an inch wide,gradually decreasing in depth forwardly, or from the heel toward thetoe. As said before, the welt is not thinned down at the ends, but isleft its original thickness, and when placed in position the. ends ofthe welt come against the rear shoulder or edge of the channel ordepression, and when stitched on the machine the threads go through theen- Specification of Letters I atent.

tire thickness of thewelt. The sol is of suflicient thickness to holdthe threads without danger of pulling out, and so are the ends of thewelt, and there 1s no chance of the threads pulling. out of either, asin the old method, wherein, as said before, the ends of thewelt arethinned down to an edge. Also by my invention the labor of skiving theends of the weltis dispensed with, thereby saving labor and reducing thecost of manufacture. The ends of the welt being of the originalthickness-that is, the same thickness as the rest of the welt-a strongerconstruetion' results, and there'is'no-danger of the shoe opening upbetween the welt and the.

Full strength of the'welt is retained and a neater and more durable jobis produced.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan View of the back or top of an outer sole before thesame is applied to the welt. Fig. 2 is an edge View of the same.

Fig.3 is a plan view of the outer sole with the welt'in place, the upperand insole being removed for the sake of clearness. Fig. 4 is an edgeview thereof. Fig. 5 is a plan view illustrating amodification.

Inthe drawings the outer sole is indicated at 6, and 7 indicates achannel cut across the same in the top or backthei'eof. At the rear edgethis channel has a squareor blunt shoulder 7, and the channel graduallydecreases upwardly and forwardly therefrom until it merges withthesurface of the sole at 7".

The welt is indicated at 8 and is firstsewed to the upper and insole.The outer sole 15 then sewed to the welt, with the ends thereof fittingor abutting against the shoulder 7 "2 These ends are of the'samethickness as the body of they welt, and the channel 7 is of proper depthto receive the same. Thesole is stitched to the welt, the stitchesindicated at 9 covering the joint between the ends of the welt and thesole at 7". It will be seen that by retaining the original thickness atthe ends of the welt the threads are not liable top'ull out, as when theends are skived down to a sharp edge.

In the modification shown in'Fig. 5 instead of cutting a channel acrossthe sole triangular incisions or depressions are cut in the sole oneachside thereof, as indicated at 10. These incisions have a shoulder atthe rear end and taper-upwardly and forwardly in similar man: ner to thechannel 7, and the welt is let into these depressions and sewed throughin the 5 outer sole sewed theretosame manner as above described withrespect to the other construction.

It is much less labor to cut a channel 7 across the sole than it is-toskive down the ends of the welt.- The invention therefore results in asaving of labor and time in addition to the other advantages referredto.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a welt shoe, an outer sole having in the shank thereof a recess ofincreasing depth toward the rear of the sole, adapted to receive theends of the welt.

2. Ina shoe, 9. welt with blunt ends, and an having a depression in theshank, of increasing depth toward the rear, into which depression theends of the welt fit.

3. In a'shoe, an outer sole having a depres sion in the shank with ashoulder at the rear, and a welt towhich the said sole is sewed, saidwelt having .blunt ends which fit in the depressien and abut againstsaid shoulder.

. In testimony whereof Ihave signed my name to this specification in thepresence of two sub 5 scribing witnesses.
